EIA Weekly Natural Gas Storage Report and Natural Gas Weekly Update

Datadory delivers eia weekly natural gas storage report and natural gas weekly update data covering lower 48 US underground working gas across the East, Midwest, Mountain, Pacific and South Central regions - current-week stocks, net change, implied flow, year-ago and 2021-25 five-year comparisons every week - plus the retired Natural Gas Weekly Update's storage-price context, delivered daily, weekly, or hourly.

What is the EIA Weekly Natural Gas Storage Report and Natural Gas Weekly Update?

It is the fastest official heartbeat in American natural gas. The Weekly Natural Gas Storage Report tracks working gas - the volume sitting in lower 48 underground storage and available for withdrawal - split across five reporting regions, each carrying six figures: current-week stocks, prior-week stocks, net change in Bcf, implied net injection or withdrawal in Bcf, a year-ago comparison, and a 2021-25 five-year average with percent changes. Its companion, the Natural Gas Weekly Update, wrapped those storage tables together with spot and futures prices and fundamentals commentary until its final edition covered the week ending January 21, 2026.

One verified week explains why desks treat it as the number of the week. For the week ending August 14, 2026: total lower 48 working gas of 3,169 Bcf, up 16 Bcf on the week, 28 Bcf below last year and 185 Bcf above the five-year average of 2,984 Bcf, with the East region at 708 Bcf against 693 the prior week and 688 a year earlier. Around eight series carry the entire readout, built from storage-operator survey responses collected on Form EIA-912.

Datadory turns that into delivered data - typed, normalized and cut to your regions and date range. Get a sample of this dataset and judge the rows before anything ships. It sits inside our gas utilities data hub beside the rest of the industry's catalog.

What do the sample rows look like?

Two observations from the verified August 14, 2026 week, exactly as they land in a delivered extract:

week_ending     : 2026-08-14
stocks_bcf      : 708       prior_week_bcf : 693
net_change_bcf  : +15       year_ago_bcf   : 688

Read the anatomy rather than the digits. The national row carries its identity on the series identifier, states its units explicitly, and pairs the level (3,169 Bcf) with the three comparisons that make it speak: week-over-week, year-over-year and against the five-year seasonal band. The regional row keeps the same week stamp and adds the prior-week anchor, so an implied-flow check is subtraction rather than archaeology. Every weekly observation you request arrives with this shape - live values for whichever regions and weeks you name.

Which fields does each weekly observation carry?

Eight fields form the spine: where the gas sits (region), how much of it there is (stocks), how the week moved it (net change and implied flow), and the three yardsticks that turn a level into a signal (year-ago percent, five-year-average percent, plus the identifiers and quality flags that make the numbers auditable).

Additional fields on request. The full payload extends past the core grid, and we pin those columns against your sample rather than promise them blind: the release envelope (release name and date, current-week, week-ago, year-ago and five-year-average stamps, fuel type, process and periodicity markers), the per-series metadata (readable name, ISO country code, unit label), the [date, value] history arrays behind each series, the South Central Salt and Nonsalt sub-columns, and the companion statistical cuts - full weekly history reaching toward the mid-1990s, five-year min/max/year-ago summaries, and the coefficient-of-variation sampling-variability series kept since April 2015. Name the analysis and the extra columns arrive mapped onto it.

What does coverage look like across geography, time and granularity?

  • Geographic: lower 48 United States aggregated into five storage regions - East, Midwest, Mountain, Pacific and South Central, with South Central additionally split into Salt and Nonsalt - plus a Total Lower 48 rollup. No state or facility-level detail exists in the public readout; the regional grain is the product.
  • Temporal: one reading per region per report week, running through the injection season (April-October) and the withdrawal season (November-March). History reaches back toward the mid-1990s, and the sampling-variability archive starts April 2015.
  • Granularity: regional weekly aggregates built from storage-operator survey responses - roughly eight series per week, each carrying its own calculated block and revision flags.

That narrowness is the point. This is not a database to explore; it is a calibrated weekly pulse, and the five-region split is what lets a Northeast cold snap be told apart from a Gulf Coast supply glut in the same Friday-morning conversation.

How is the data delivered?

API, files, or your warehouse. Daily, weekly, or hourly.

You pick the channel and the cadence; parsing, typing and schema stability stop being your problem. Because the source moves weekly, most teams take the full history once as a backfill - every region back toward the mid-1990s in one pass - and keep new report weeks rotating in on whatever rhythm their models expect. Whichever way you take it, the eight-field spine travels unchanged, and the revision flags ride along so a reprinted figure never masquerades as a fresh one. A sample ships first either way, sized to test inside your pipelines the same day.

Who uses this data, and for what?

  • Trading the weekly print - the injection or withdrawal is measured against consensus expectations before positions move; see investors quants use cases.
  • Dashboard ingestion - working-gas levels with year-ago and five-year bands drop straight into monitoring panels and feature stores; see data scientists use cases.
  • Market-moving journalism - report the number markets moved on, with the five-year context that makes it quotable; see journalists academics use cases.
  • Product wiring - a fixed weekly rhythm and a stable field spine make scheduling trivial; see developers builders use cases.
  • Price commentary and winter planning - storage swings explain near-term price moves, and season-to-date deficits gauge heating-demand strength; see market sizing applied to utility territories and price monitoring for the wider pattern.

Which personas get the most value?

Investors and quant researchers (relevance 3 of 3) get a weekly, consensus-comparable inventory signal with revision transparency attached. Data scientists and ML engineers (3 of 3) get a clean eight-series panel whose five-year band is already computed - no seasonal baseline engineering required. Journalists, academics and students (3 of 3) get the single most-cited weekly number in energy, attributable to an official statistical agency. Developers and data-product builders (2 of 3) wire a stable schema on a fixed rhythm. Market researchers and consultants (2 of 3) anchor energy-price commentary in inventory arithmetic, and sales and growth teams (1 of 3) time utility and large-commercial outreach against winter demand strength.

What should I know before requesting a sample?

Three things worth settling upfront. First, scope: state which regions and which season window your analysis needs - the five-region grid, the South Central Salt/Nonsalt split, or the national rollup - and the sample lands pre-cut. Second, lineage: the Natural Gas Weekly Update stopped at the week ending January 21, 2026, so teams wanting its former spot-price and commentary layers should say so; those pair naturally from our price-side extracts while the storage series continues under the successor supplement launched January 29, 2026. Third, revisions: values can be revised or reclassified between reports, and the per-metric flags travel with every row, so downstream models can distinguish a corrected number from a new one. Tell us the decision the data feeds and the sample arrives shaped around it.

Which datasets sit next to this one?

Cards worth reading next: the monthly ledger behind the weekly pulse, the portal that aggregates the whole statistical system, the European flow mirror, and the primers that decode the vocabulary.

EIA Natural Gas Monthly repackages supply, disposition, storage and prices as a 25-table monthly publication - breadth where this record has speed. EIA Natural Gas Data Portal aggregates production, imports, storage and pricing behind one front door when a single weekly indicator is too narrow. ENTSOG Transparency Platform is the European counterpart for flows and capacity at gas-day grain - movement, not inventories. Against Eurostat Natural Gas Supply Statistics the choice is a weekly US inventory pulse versus monthly EU macro balances, and our head-to-head comparison scores both line by line. For vocabulary: what working gas actually measures, how the EIA Weekly Natural Gas Storage Report fits together, and where this record ranks on the best gas utilities datasets list.

Questions buyers ask

What does one week of the storage report contain?

Six figures per region: current-week working gas stocks, prior-week stocks, the net change in Bcf, implied net injection or withdrawal in Bcf, the year-ago comparison with percent change, and the 2021-25 five-year average with percent change. Roughly eight series cover the whole lower 48 readout, each stamped with its report week and revision flags.

Which regions does the lower 48 split into?

Five: East, Midwest, Mountain, Pacific and South Central, with South Central further divided into Salt and Nonsalt caverns, plus a Total Lower 48 rollup. The regional cut is what makes the number diagnostic - a Northeast deficit and a Gulf Coast surplus produce very different national totals.

How far back does the storage history reach?

Full weekly history reaches toward the mid-1990s, giving roughly 1,600-plus weekly observations per region for multi-year seasonality work. A coefficient-of-variation sampling-variability series runs separately from April 2015, and five-year min/max/year-ago summaries sit alongside the main table.

What do the revision and reclassification flags mean?

Each metric carries booleans marking whether its value was revised versus the previously published figure or reclassified between categories. Treating those flags seriously is the difference between modeling a genuine inventory swing and accidentally training on somebody's correction.

What happened to the Natural Gas Weekly Update?

Its final edition covered the week ending January 21, 2026. The storage tables live on under the Weekly Natural Gas Storage Supplement launched January 29, 2026, while spot and futures price context moved to dedicated series. Datadory stitches both sides so a continuous record survives the handover.

Can a sample be cut to specific regions, seasons or years?

Yes. Name the regions - including the Salt/Nonsalt split - the season windows and the year range, and the sample arrives in the exact eight-field shape documented above, with the extended envelope columns mapped where your analysis needs them. Anything built against the sample carries unchanged into the production feed.
